Light- and electron microscopic studies of the liver in "bronze baby" syndrome.

The light- and electron-microscopic changes of the hepatic tissue of a case with the "bronze baby" syndrome were described. The light-microscopic examinations revealed intrahepatic cholestasis of the hepatocanalicular type associated with portal inflammation. The electron-microscopic examinations showed dense deposits in the hepatic cells, Kupffer cells and in the bile canaliculi. The bile canaliculi were distended, the canalicular membrane severely destructed. The patient included in the study has been free of symptoms for 2 years.
